What’s in vape juice?

If you’re wondering what’s in this stuff, you’ve found the knowledge you’re looking for!

What’s in vape juice, anyway? The answer is: not much. Most vape juices contain varying amounts of the following.


  • Water
  • Vegetable Glycerin (VG)
  • Propylene Glycol (PG)
  • Nicotine
  • Flavoring

That’s it! Different juices have different amounts (or concentrations) of each of the above. Water, vegetable glycerin, and propylene glycol form the base, and the much smaller amounts of flavoring and nicotine are added for obvious reasons. Now for the breakdown of the most mysterious chemicals in vape.

  • Vegetable glycerin (VG): vegetable glycerin is a thickener and sweetener used in many foods, and is safe for consumption. It’s made from vegetable oil, and it produces dense clouds of vapor.
  • Propylene glycol (PG): propylene glycol is a clear liquid used to carry flavors in food products, and is also safe for consumption. It doesn’t produce as much vapor as VG, but it does allow for a purer flavor experience, although it must be vaped at lower temperatures – it produces a sharper throat hit as well.

Many juices contain vegetable glycerin and propylene glycol in 40/60 or 60/40 ratios, respectively. Many juices are also half-and-half. If you want more clouds, you want a 40% PG, 60% VG juice, and if you want purer flavors, go with the opposite: 60/40 PG/VG. Juices that use 100% PG or 100% VG are available, but blends are popular because they balance the cloud density, flavor, and throat hit properties of each. That’s all the basics of vape ingredients, we’ll have much more info in future posts.
